| * [PATCH] sky2: revert pci express extensionsStephen Hemminger2006-10-112-24/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The pci express error handling extensions don't work unless PCI access is via mmconfig. Otherwise, all accesses to pci config registers greater than 256 fail. Since the sky2 driver has other ways of getting to PCI config space, it works around this short coming, but the pci_find_ext_capablity doesn't work. This backs out commit 91aeb3edbcf4e6ed72d138ac8c22fd68e6d717c3 Go back to hardcoding, since we know where the error registers are anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The transmit side of the spider ethernet driver currently places locks around some very large chunks of code. This results in a fair amount of lock contention is some cases. This patch makes the locks much more fine-grained, protecting only the cirtical sections. One lock is used to protect three locations: the queue head and tail pointers, and the queue low-watermark location.

| * [PATCH] powerpc/cell spidernet low watermark patch.Linas Vepstas2006-10-112-4/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement basic low-watermark support for the transmit queue. Hardware low-watermarks allow a properly configured kernel to continously stream data to a device and not have to handle any interrupts at all in doing so. Correct zero-interrupt operation can be actually observed for this driver, when the socket buffer is made large enough. The basic idea of a low-watermark interrupt is as follows. The device driver queues up a bunch of packets for the hardware to transmit, and then kicks the hardware to get it started. As the hardware drains the queue of pending, untransmitted packets, the device driver will want to know when the queue is almost empty, so that it can queue some more packets. If the queue drains down to the low waterark, then an interrupt will be generated. However, if the kernel/driver continues to add enough packets to keep the queue partially filled, no interrupt will actually be generated, and the hardware can continue streaming packets indefinitely in this mode. The impelmentation is done by setting the DESCR_TXDESFLG flag in one of the packets. When the hardware sees this flag, it will interrupt the device driver. Because this flag is on a fixed packet, rather than at fixed location in the queue, the code below needs to move the flag as more packets are queued up. This implementation attempts to keep the flag at about 1/4 from "empty".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes eeprom read on big-endian architectures. readw returns the data in CPU order. With cpu_to_le16 we convert it to little endian, because "ptr" is a pointer to a _byte_ arrray. See the cast above. A byte array is little endian. The bug is: Reading u16 values with readw, casting them into an u8 array and accessing this u8 array as an u8 (byte) array. The correct fix is to swap the CPU-ordering value returned by readw into little endian, as the u8 array is little endian. This compiles to nothing on little endian hardware (so it does not change b44 code on LE hardware), but _fixes_ code on BE hardware.

The consumer_index and producer_index are u32's that get incremented on every buffer emptied and replenished respectively. We use the {producer,consumer}_index mod'ed with the size of the pool to pick out an entry in the free_map. The problem happens when the u32 rolls over and the number of the buffers in the pool is not a perfect divisor of 2^32. i.e. if the number of 2K buffers is 0x300, before the consumer_index rolls over, our index to the free map = 0xffffffff mod 0x300 = 0xff. The next time a buffer is emptied, we want the index to the free map to be 0x100, but 0x0 mod 0x300 is 0x0. This patch assigns the mod'ed result back to the consumer and producer indexes so that they never roll over. The second chunk of the patch covers the unlikely case where the consumer_index has just been reset to 0x0 and the hypervisor is not able to accept that buffer.

The proc file is created when the device is probed, so a change in the name of the device will not be reflected in the name of the proc file giving problems when identifying and removing the adapter.

| * | [PATCH] ibmveth: Harden driver initilisationMichael Ellerman2006-10-051-6/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has been floating around for a while now, Santi originally sent it in March: http://www.spinics.net/lists/netdev/msg00471.html After a kexec the ibmveth driver will fail when trying to register with the Hypervisor because the previous kernel has not unregistered. So if the registration fails, we unregister and then try again. We don't unconditionally unregister, because we don't want to disturb the regular code path for 99% of users.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous change to do fragmented receive (post 2.6.18) introduced a bug where packets are passed up with size set to the size of the receive buffer not the actual received data. IP silently trims this so it didn't show up right away. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - fix: toshoboe_invalid_dev() was recently removed, but not all callers were updated, causing the obvious linker error. Remove caller, because the check (like the one removed) isn't used. - fix: propagate request_irq() return value - cleanup: remove void* casts - cleanup: remove impossible ASSERTs Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
